SPECIFICATION forming part of Letters Patent lilo. 793,836, dated July 4, 1905. Application filed January 18, 1905. Serial No. 241,660.

To all when/i, it mm1/y concern,.-

Be it known that l, ULrvEn CLARK KING- CAID, a citizen of the United States, residing at Fairmont, in the county of Marion and State of West Virginia, have invented a new and useful VVater-Closet, of which the following is a specilication.

This invention relates to waterclosets, and more particularly to that class ol closets which are provided with tra p-valves arranged to be operated automatically by the llushing et the closet-bowl.

Among the objects of the invention are to provide a valve capable of being operated l'or the passage of water by the raising ol" the lid, and teso constructsaid valve as to cause it to be automatically seated by the pressure oil water passing through the valve-casing, thus automatically closing the lid.

A further object is to so counterbalance the lid that the closure thereof shall be e'li'ected by a comparatively slight water-pressure, provision being also made for regulating the counterbalance-weight.

l/Vith these and other ends in view, which will readily appear as the nature of the in.- vention is better understood, the saine consists in. the improved construction and novel arrangement and combination et parts, which will be hereinafter 'fully described, and particularly pointed out in the claims.

ln the accompanying drawings, Figure l. is a vertical transverse sectional View of a closet constructed in accordance with the l)rinciples o'l" the invention. Fig. 2 is a sectional view taken on the plane indicated by the line 2 2 in Fig. l. Fig. 3 is an enlarged sectional View of the valve. Fig. 4 is a detail plan view olE the counterbalance-weight. Fig. 5 is a horizontal sectional detail view taken on the line 5 5 in Fig. l, one of the valve members having-been removed. Fig. 6 is a perspective detail view ol the valveamerating member.

orresponding parts in the several ligu res are indicated by like characters of reference.

The outer casing l of the device is preferably constricted intermediate its upper and. lower ends, presenting a hoppr-n'shaped upper portion or member 2, the lower end oi' which allords a seat Alor a diaphragm $5, hav-- ing a depending annular llange 4l, with which the soil-pipe 5 is connected. The diaphragm 3 has a central llanged aperture the [lange 7 ol! which a'll'ords a seat lor the lower end of the bowl S. The diaphragm 5 is provided adjacent to opposite sides el" the central aperture 6 with a pair oil slots 9 l), countersunli, as at Q, and through which extend the stems l() l0, carrying the valve members Il ll, which when closed co'nwratc to lorm 'an approximately senlispherical. cup which constitutes a tightly-litting closure for the opening at the lower end ollv the bowl. .lhe stems l() have a rocking or pivotal movement in the slots l), and they are provided at their upper ends with wings or enlargements l2, consti.- tuting countcrwcights, whereby the closure o'l" the valve composed ol5 the members ll is ell'ccted, said weights or extensions being readily acconnnodated in the space between the bowl and the outer casing. The valve `membi-nfs ll are preferably bolted, riveted, o1' otherwise suitably connected with the stems l0, which latter are thereby retained in the notches S) without possibility ot displacement and without the necessity l'orpivotal pins.

Suitablysupported, as by a cross-brace l2, in the space between the bowl and the outer casing, which. latter may be provided with a bulging portion, (shown at 13 in Fig. 2,) a valve-casing ladiaving an inlet 115 whiehcommunicates with the upper end thereof and an outlet l@ comnnmicating with. itsmlower end. The inlet 'l5 is connected with the service-mpc 1l 7, and the outlet ,l is connected by a pipe l 8 with an annular flushing-pipe 19, supported at the upper end el. the bowl and having a plurality oil dischargeoilienings 2() in the under side thereo'l". rlaid i'lnshing-pipe may be partially accommodated in a groove or recess in the under side ol the seat 2l, which .is supported upon the upper end oli' the casing and which is provid ed wi th a hinged l id 22.

The valve-casing is provided with an interior seat 23 :tor an upwardly-Opernng valve 24;, having a stein 25, which suitably guided in the casing. The lower end olf the latter has a packing-gland 26, tlrrough which ea:-

tends an operating-rod 27, the upper end of which supports the lower end of the valvestem, so that by an upward movement of the rod 27 the valve will be raised from its seat against the pressure of the water entering through the inlet 15. The valve-operating rod 27 is formed by the short arm of an approximately U-shaped casting or member, the long arm of which, 2S, is disposed in rear and exterior of the valve-casing, being connected with the latter by means of a pin or bolt 29, extending through a slot 3() in the arm 28 and connected with the valve-casing, thus permitting the U-shaped member, which includes the valve-operating rod, to have a limited reciprocating movement. The upper end of the arm 2S has a lat-eral extension 31, which is disposed in the path of a hook 32, connected with the rear end of the lid 22.

The U-shaped member, which includes the rod 27 and the arm 28 and which as a wholeV is designated R, is provided with a counterweight, which is in the nature of a ring 33 having disconnected ends which are provided with lugs 34g, which are bolted or otherwise secured to the lower end of the member R. The ring-shaped member 33 extends entirely around the bowl, and it is provided with one or more threaded apertures 35 for the reception of fastening members 36, whereby auxiliary weights, as 37, maybe connected with the ring 33 for the purpose of augmenting the weight of the latter.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood.

Then the closet is not in use, the lid, being automatically operated, as will be presently described, is necessarily closed, and the valve, composed of the members 11, likewise forms a tight closure between the bowl and the soilpipe, thus preventing not only the passage of sewer-gas, but also of backwater, which is sometimes an important consideration. The hook 32 is so disposed with relation to the lateral extension or catch of the member R that it shall not engage said catch until the lid is raised to an approximately vertical position, as shown bydotted lines av a in Fig. 2. Then the lid is swung beyond an approximately vertical line to a position approximately indicated by dotted lines Z) I) in Fig. 2, the hook 32 operates against the catch 31 to raise or elevate the member R, together with the counterweight 33, connected with said member, said counterweight being calculated to counterbalance the weight of the lid. Then the member R is thus elevated, the rod 27, which forms a part of said member, will push in an upward direction upon the valve-stem 25, raising said valve from the seat and permitting water to pass from the service-pipe 17 through the valve-casing and the pipe 1S to the flushing-pipe 19 and thence into the bowl. The valves 11 will immediately open under the pressure of the water for the passage of water and soil. As soon as pressure upon the lid in the direction of the arrow in Fig. 2 is discontinued the said lid will be automatically closed by the action of the water passing through the valve-casing 14 and impinging upon the upper side of the valve 2-1 and forcing the latter to its seat, thus lowering the member R and causing the catch 31 at the upper end of the arm 28 of said member to exert downward pressure upon the hook 32, connected with the lid. It is obvious that only a comparatively light waterpressure will be needed to perform this service automatically, the lid being practically counterbalanced by the weight member 33.

It will be observed that in this improved closet the water trap or seal is done away with and that there are no parts liable to be rendered inoperative through freezing as long as the surface-pipe is open. Springs, whether of rubber or metal, are entirely avoided in the construction of this device, the parts of which cooperate easily and efficientlyto bring about the desired results.

It is desired to be understood that while in the foregoing a simple and preferred form of embodiment of the invention has been shown no limitation is necessarily made to the precise structural details herein described, but that the right is reserved to any changes, alterations, and modifications which maybe resorted to within the scope of the invention and without departing from the spirit or sacrificing the efficiency of the same.
